18365-29-2

Triphenylphosphine oxide-nitric acid complex is a chemical compound formed by the interaction of triphenylphosphine oxide (P(C6H5)3O) and nitric acid (HNO3). Triphenylphosphine oxide is an organophosphorus compound, characterized by a phosphorus atom bonded to three phenyl groups, and it is often used as a ligand in coordination chemistry. Nitric acid, a strong acid, is known for its oxidizing properties. The complex formed between these two substances combines the reactivity of both components, resulting in a compound that can be used in various chemical reactions, particularly in oxidation processes. The exact structure and properties of the complex can vary depending on the stoichiometry and conditions under which it is formed, but it generally serves as a source of the triphenylphosphine oxide ligand in reactions where nitric acid's acidic and oxidative properties are also required.

18365-29-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18365-29-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,6 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18365-29:
(7*1)+(6*8)+(5*3)+(4*6)+(3*5)+(2*2)+(1*9)=122
122 % 10 = 2
So 18365-29-2 is a valid CAS Registry Number.

Reaction of stabilised phosphorus ylides with nitrogen dioxide

Aitken, R. Alan,Karodia, Nazira

, p. 251 - 254 (1999)

The reaction of the stabilised ylides 14-23 with an excess of NO2 in CH2Cl2 at room temperature gives different results depending on the structure of the starting ylide. The monacyl ylides 14-16 give the corresponding α-oxo nitriles 4 together with Ph3PO · HNO3 (24) which has been fully characterised for the first time. Under the same conditions, the ylide 18 gives 2,4-dinitrobenzonitrile (26), Ph3PO, and benzoic acid. The other ylides examined all give 24 together with a variety of other products.
